How Compost is Made
The compost is produced at the city’s compost facility located at the end of Davidson Drive. It is a mixture of wood chips and dehydrated biosolids from the city’s wastewater facility. The compost analysis consists of:
- Moisture - 56%
- Nitrate nitrogen - <0.5 mg/kg
- pH - 7.6 S.U.
- Phosphorus - 12,000 mg/kg
- Potassium - 14,000 mg/kg
- Salts - 21.0 mmhos/cm (millimohs per cm)
- TKN - 19,000 mg/kg
Sometimes called "black gold," compost gives plants a boost when added to soils.
- Improves the soil structure, porosity and density, thus creating a better plant root environment
- Increases infiltration and permeability of heavy soils, thus reducing erosion and runoff
- Improves water holding capacity, thereby reducing water loss and leaching
- Supplies a variety of macro and micro-nutrients
- May control or suppress some soil-borne pathogens
- Supplies significant quantities of organic matter
- Improves cation exchange capacity (CEC) of soils and growing media, thus improving the holding of nutrients for plant use
- Improves and stabilizes soil pH
- Can bind and degrade specific pollutants @(Model.BulletStyle == CivicPlus.Entities.Modules.Layout.Enums.BulletStyle.Decimal ? "ol" : "ul")>
Compost has a variety of uses, such as general landscaping, flower beds, house plants, gardens, lawns, shrubbery, trees, etc. Below are some examples of how to mix and measure compost.
- Established Lawns - Apply 3/4 to 1 cubic yard of compost per 1,000 square feet, to a depth of 1/4 to 3/8 inch. This is best done in early spring and late fall when conditions are cool and moist.
- New Lawns - Apply 3 cubic yards per 1,000 square feet to a depth of 1 inch and rototill to a depth of 4 to 6 inches.
- Flower Boxes and House Plants - Mix two parts compost, one part peat moss, and 1 part perlite or vermiculite.
- Flower Beds - Apply 3 cubic yards of compost for every 1,000 square feet to a depth of 1 inch.
- Vegetable Gardens - Apply 1 cubic yard per 1,000 square feet, once per year in late fall or winter.
- Recommendations - We recommend you wear garden gloves when working with compost and other garden materials. @(Model.BulletStyle == CivicPlus.Entities.Modules.Layout.Enums.BulletStyle.Decimal ? "ol" : "ul")>
